I have always been lucky going out of MAN, no problems, but coming back is something else.
Last year waited 30 mins and 45 mins just to get the disembarking gate connected. Both times the handling agent said it was because we had arrived too early!!
The wait for baggage has to be one of the worst of all major airports, often been in the only group waiting for baggage in T2 and it still takes more than an hour..
